Specification of Letters Patent.

Patented Mar. 14, 1911.

Application led April 19, 1910. Serial No. 556,318.

To all 'whom it may concern:

Be it known that I, BERNARD NEALIs, a citizen of the United States, and a resident of Fulton, in the county of Oswego and State of New York, have invented a new and Improved Rosette, of which the following is a full, clear, and exact description.

The invention has in view a resilient support for electric lights, more particularly a support in the form of a hanger, and in connection with or forming a part `of what is ordinarily known as a tungsten lamp.

The filament of the tungsten lamp is of such delicate nature that it can withstand little shock, and to increase the life of the,

lamp I have devised the present device, the same having for its purpose, in addition to providing a yielding support, to eliminate the possibility of the conductors contacting with the fastening screws, and tomake it unnecessary to remove the cap of the rosette in applying or removing these screws.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side view of a rosette constructed in accordance with my invention, the rosette being shown applied to a ceiling, and supporting, through the conductors, a tungsten lamp; Fig. 2 is a central vertical section of the rosette; Fig. 3 is a like section at right-angles to the section shown in Fig. 2; Fig. 4 is a plan vof the base of the rosette, with the binding post-s for the line wires removed; Fig. 5 is an upper end view of the rosette cap; Fig. 6 is a lower end view of the rosette cap, with the spring bolt or hanger removed; Fig. 7 is a central vertical section through the rosette base, on the line 7-7 in Fig. 4, showing the base in an inverted position; Fig. 8 is a central vertical section on the line 8 8 in Fig. 5, of the rosette cap wit-h the spring hanger or bolt removed, and otherwise stripped of the trimmings; Fig. 9 is a plan of the conductor clamp carried by the hanger or bolt; and Fig. 10 is an upper face view of the rosette base.

In carrying out my invention I employ a rosette base 15, the same having the customary central recess 16 in its under face, and the outwardly-extended lugs 17 at diametrically opposite points, iiush with the upper face of the base, under which the binding posts 18 extend for receiving the line wires 19, this construction of the base being in all respects the same as the base of the rosette now in use. However, the base 15 diers from the conventional rosette base in that instead of having the openings for the fastening screws at theinside -of that portion of the base inclosed, the same are formed in outwardly-extending lugs 2O arranged flush with the upper face of the base and in a line at approximately right-angles to a line passing through the lugs 17. This arrangement of the openings for the fastening screws permits of the latter being applied and removed while the rosette remains assembled.

The rosette cap 21 is shown to be detachably applied to the base 15 in the usual way, as by means of the outwardly-extended contact pieces 22, which bear on and are fastened to the binding posts 18. The cap 21, unlike the ordinary rosette cap, has a relatively long depending shank or neck having a central longitudinal opening 23 of reduced diameter at a point near the bottom, providing a shoulder 24. Within this opening 23 of the cap is slidably mounted a hanger or bolt 25, the latter having a head fitting the upper enlarged portion of the opening and between which and the shoulder 24 is interposed a spring 26, by which the hanger is resiliently supported. The hanger or bolt extends a substantial distance below the lower end of the cap, where it is provided with a conductor clamp 27, tle clamp consisting of two clamping blocks or jaws secured transversely of and at opposite sides of the bolt by a thumb-screw 28, each jaw having central vertical grooves 29 at the center to fit around the bolt, and similar but smaller grooves at each side of the clamping Ascrew for receiving and binding on the conductors 30 leading to the tungsten lamp 31. The conductors 30 instead of passing out centrally through the cap, as is the usual practice, pass from the binding posts 32 to the outside of the cap at the opposite sides of the rosette, and are coiled or made sufriciently full between the binding posts 82 and the clamp 27, as shown in Fig. 3, so as not to interfere with the free yielding movement of the bolt or hanger 25. The binding posts 32 are shown to be fastened to the rosette cap and electrically connected with the binding posts of the contact pieces 22 in the usual way.

With the rosette constructed as shown and the rosette, and also the bolt or hanger 25 and the conductor clamp, are made of an insulating material, preferably porcelain.

Having thus describedV my invention, I

claim as new and desire to secure by Letters Patent 1. The combination "of a rosette base, Va rosette cap detachably connected to the base, a lamp hanger vertically movable within the cap, a spring supporting the hanger, and

- a conductor clamp secured `to the lower end of the hanger.,

2. The combination of a rosette base, a rosette cap detachably applied to the base, a lamp hanger slidable in the cap, a spring seating in the cap, on which the hanger is supported, and a conductor' clamp .having `separable aws bindingly secured-at the opposite sides of the hanger below the cap;

3. The combination of a rosettek base, a

rosette cap detachably applied to the base, having conductor openings at the upper portion leading outwardly at the opposite sides of the cap, a resilient lainp hanger supported from the cap, and a conductor clamp arranged to receive the conductors, passing through the said openings and applied to the hanger below the cap.

'4. The lcombination. of la rosette base, a rosette cap detachably secured to the base, having a relatively long depending neck, a lamp hanger vertically movable within the neck, a spring arranged within the neck of the cap'and supporting the hanger, and a conductor clamp applied to the lower end of the hanger below the cap.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
